39304110 ÷ 398 
Our goal is to divide 39304110 by 398.

Going ahead to step 1:
398 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 398

Step 2:
If we divide 39 by 398, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 398

On to step 3:
The number 398 fits into 393 0 times, leaving a remainder of 393.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 393 leaves us with 393.
Fetch the next digit (0) from the dividend, attach it to 393 and continue: 3930 / 398

On to step 4:
When dividing 3930 by 398, we get 9 with a remainder of 348.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 3582 from 3930 and we're left with 348.
Bring next digit (4) of the dividend behind the 348 and repeat the process: 3484 / 398

Let's proceed to step 5:
398 goes into 3484 8 times with a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Deduct 3184 from 3484 and we're left with 300.
Grab the next digit (1) from the dividend, add it to 300, then carry on: 3001 / 398

On to step 6:
398 goes into 3001 7 times with a remainder of 215.
The number 7 becomes the next digit in our result. 
Result so far: 987.0
Deduct 2786 from 3001 and we're left with 215.
Fetch the next digit (1) from the dividend, attach it to 215 and continue: 2151 / 398

Moving on to step 7:
2151 divided by 398 is 5 with a remainder of 161.
Put 5 as the next digit of the answer. 
Result so far: 9875.0
Subtracting 1990 from 2151 leaves us with 161.
Fetch the next digit (0) from the dividend, attach it to 161 and continue: 1610 / 398

Advancing to step 8:
The number 398 fits into 1610 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 98754.0
Subtract 1592 from 1610 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
180 divided by 398 is 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 98754.0
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
1800 divided by 398 is 4 with a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 98754.04
Subtract 1592 from 1800 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 11:
If we divide 2080 by 398, we get 5 and a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 98754.045
Subtract 1990 from 2080 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
900 divided by 398 is 2 with a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 98754.0452
If we subtract 796 from 900, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 13:
The number 398 fits into 1040 2 times, leaving a remainder of 244.
Record the quotient 2 as the next digit in the result. 
Result so far: 98754.04522
Subtract 796 from 1040 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

In conclusion, the division gives 98754.04522 with a balance of 0.000244.
